최인범,정용승 경기대학교 1995 論文集 Vol.37 No.-

We made an analysis of correlation and an analysis of variance to grasp the difference of physical fitness among weights and the correlation of physical fitness and sports career in Taekwondo, making the subjects of 24 high school players light weight class-9, middle weight class-9, and heavy weight class-6, who live in cheong ju city. The results are as follows ; 1) There was a significant difference in almost items among 3 group in the test of physique. There was a lot of deviation in girth of chest, length of leg, girth of thigh and skinfold thickness. 2) When Tae kwon do players were heavier in the test of physical fitness, there was a significant difference in grip strength and back strength and no significant difference in dipping, pull-up. Especially agility, flexibility and power were shown to be higher in light weight class than heavy weight class. 3) In the correlation of physical fitness and sports career, when they had lots of careers, there were certain correlations in dipping, shuttle run, burpee test and trunk flexion. Especially there was the contray correlation in back strength, sargent jump, trunk extension, when they had lots of careers. 4) In the analysis of variance about physical fitness factors among weight, there was no significant difference in grip strength, back strength, agility, but there was a significant difference in pull-up and harvard step test.

Parallel combination, little significance is given on performance of Recognizer but its performance depends on how to combine. In the serial combination, the results of the Recognizer are ignored and different results can be produced. And, performance even after combination is not much improved compared with that of a single Recognizer. Therefore, this study aims to make up for methods of combination of multi recognizer shortcomings menthioned above. That is, we use an advantage of parallel Recognizers, using two or more resultant values, and those of Recognizers of the serial combination, considering supplements of recognizers and a point of several steps of verification. Therefore, this study tend to suggest the results of research and experiments on methods of recognize the combination of the results from three nodes of recognizers which in parallel are linked in the form of total three pipeline.

Lutembacher's syndrome is rare combination of mitral stenosis (MS) and atrial septal defect (ASD). The hemodynamic interplay between the MS and ASD leads to wide variation of clinical presentation. Here we describe a 43-year-old female with Lutembacher's syndrome and tricuspid regurgitation with pulmonary hypertension, who underwent direct closure of ASD and tricuspid valvuloplasty successfully. We also reviewed other literatures in an effort to increase awareness of this condition.

Bipolar disorder, like epilepsy and migraine, is episodic in nature and psychiatric illness requiring lifelong treatment. So, it should not be surprising that anticonvulsants such as carbamazepine and valproate have proven efficacy as mood stabilizers. The newer anticonvulsants such as lamotrigine, gabapentin, topiramate, oxcarbazepine, tiagabine, and zonisamide may also be effective treatments for bipolar disorder. Identifying an anticonvulsant for use in bipolar disorder should take into account not only the pathophysiology of bipolar disorder but also the mechanism of action of the anticonvulsant. Evidence for effectiveness of these novel antiepileptic drugs in treating acute mania and depression as well as in preventing the recurrence of mania and depression is reviewed. In conclusion, although the novel anticonvulsants appear to be clinically useful, more controlled trials are needed to assess the effectiveness in bipolar disorder.

The hydrogen production was investigated by using the cattle manure with and without pretreatment as the substrate. Heat treatment (50, 80, 120℃), initial pH control and acidic hydrolysis was used pretreatment. Without pretreatment, the hydrogen production was limited. By the Pretreatment with 0.5% HCI at 121℃. 20 min, about 45-55% of solid carbohydrates were hydrolyzed. In the batch test using hydrolyzed liquid, hydrogen production was 1.76 L/L and the degradation efficiency of carbohydrate was above 90%. In the continuous experiment, hydrogen was produced continuously. Hydrogen production rate was 3 L/L/day during the steady condition. The main organic acids were acetic acid and butyric acid.

This paper presents new current-mode CMOS multiple-valued integrated circuits for high-density arithmetic systems. The validity and effectiveness of the proposed circuits are verified through the HSPICE simulation. A 8×8-bit parallel multiplier using the proposed circuits with 2V supply voltage is designed with a 0.25㎛ standard CMOS technology. The performance of the proposed multiplier is evaluated to be about 74% smaller than that of a corresponding binary implementation.

Causes of atelectasis under general anesthesia are tracheal foreign body, blood clot, aspiration of bronchial secretion, one-lung ventilation and relative predominance of parasympathetic system. N-acetylcysteine is mucolytic agent which improves the capability of sputum drainage. After administration of N-acetylcysteine, an increased volume of liquified bronchial secretions may occur. When cough is inadequate, the airway must be maintained open by mechanical suction. In case that is a mechanical block due to local accumulation, the airway should be cleared by endotracheal aspiration. A 49-year-old female was admitted for bilateral laparoscopic oophorectomy due to ovarian tumors. There was not any problem during a general anesthesia induction. After instillation of N-acetylcysteine into endotracheal tube, acute atelectasis was developed in right lower lung.

We selected at random 30 geriatric patients who had received operation under the general anesthesia with endotracheal intubation. The patients were divided into 3 groups. Group 1 (control) had received endotracheal intubation without diazepam and lidocaine. Group 2 had received endotracheal intubation with diazepam. Group 3 had received endotracheal intubation with lidocaine. The changes of arterial blood pressure and pulse rate, and the appearance of arrhythmia were compared in each group. The results were as follows : 1. The increase of blood pressure and heart rate were less in group 2, 3 than the control group which showed significant increase of blood pressure and heart rate with endotracheal intubation. 2. The incidence of arrhythmias with endotracheal intubation was less in group 2(20%), group 3(50%) than the control group(80%). 3. The electrocardiographic change in the group 2 and 3 were not significant compared to group 1(control).

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

In recent years, depression is most commonly reported psychiatric condition after stroke, poststroke depression(PSD) has attracted world-wide interest. This review focuses on the major research themes that have emerged. Pooled data from studies, have wide variation in results is due to different criteria for patient selection, different evaluation methods, diagnostic criteria and poststroke intervals, conducted throughout the world have found prevalence rates for from 18% to 65%. The diagnosis of PSD is most appropriately based on a structured mental state exam and DSM-N criteria for depression due to stroke with major depressive-like episode or depressive features. Rarely, poststroke patients may also develop bipolar mood disorder. The treatment of PSD, single antidepressant showing efficacy and electroconvulsive theraphy(ECT) and behavioral therapies have also effective. The progression of recovery following stroke can be altered by treating depression, which has been shown to improve recovery in activities of daily living(ADL) and cognitive impairment and to decreased mortality. The mechanisms underlying the association of stroke and mood disorder are important areas for future investigation.
